Problems solved by technology

However, due to the poor structural strength of the plastic material, the casing 13 is easily deformed by the pushing of the concrete during the grouting process, that is, the aforementioned patents cannot provide openings with better dimensional accuracy
This kind of lack that will be produced during molding will not cause problems in use when used in conjunction with "raised floors". However, if the concrete floor is to be used directly as a floor, the aforementioned casing 13 that has been squeezed and deformed will It is difficult to cover items such as: cover plates

Embodiment Construction

[0039] refer to image 3 , Figure 4 and Figure 5 A preferred embodiment of the molding device of the present invention is installed on a formwork 21. When concrete is poured above the formwork 21 and solidified, a concrete floor 22 can be formed, and holes are preset on the floor 22. The concrete floor slab can be a general on-site construction floor slab or a precast floor slab.

[0040] The molding device of the present invention includes: several first molding assemblies 3, several second molding assemblies 3' and several conductive units 30 connected between these molding assemblies 3, 3' and having electrostatic grounding function. Wherein the conductive unit 30 includes: two metal conductive parts 301 respectively fixed on the molding assemblies 3, 3', a copper wire 302 connected between the conductive parts 301, and a first The ground wire 303 of the molding assembly 3 is grounded, so that the metal components on the molding device have the function of electrostati...

Abstract

The invention provides a method for constructing preformed holes on a concrete floor slab of a dustless factory building. The method can be carried out in the way of precasting the concrete floor slab having preformed holes in advance at a construction site other than the scheduled site for a building, then moving the concrete floor slab to the field of the scheduled site for a building to assemble, or the method can also be carried out in the way of directly constructing the concrete floor slab having preformed holes on site at the scheduled position of the floor slab of a building. The method comprises the steps of (1) fixing a fixing unit on a template, (2) sleeving a casing pipe on the fixing unit, (3) sleeving an underlay component above the casing pipe, (4) grouting the underlay component to form the floor slab, and (5) sleeving a cover plate above the underlay component, wherein the cover plate is used as a floor face of the concrete floor slab of a building.

Description

technical field [0001] The invention relates to a construction method for reserving openings on concrete floors, in particular to a construction method of directly fixing some components of a forming device on the concrete floor and reserving openings on the concrete floor. Background technique [0002] refer to figure 1 , 2 Shown is the three-dimensional exploded view and combined cross-sectional view of the invention of Taiwan, China, No. 449634, which was applied for by the applicant. The molding device 1 of the aforementioned patent is installed on a template 10, including: a base 11, several bases 11 screw 12 fixed on the template 10, a hollow sleeve 13 axially sleeved on a ring support wall 111 of the base 11, a top cover 14 located above the sleeve 13, and a connecting base 11 and The coupling mechanism 15 of the top cover 14 . Wherein the connecting mechanism 15 includes: a rod-shaped threaded piece 151 , and a nut 152 which is under the base 11 and can be screwed...
